MediaTek Unveils Dimensity 9400 Flagship SoC

MediaTek has launched the Dimensity 9400, the company’s new flagship smartphone chipset optimized for edge-AI applications, immersive gaming, incredible photography, and more. The Dimensity 9400, the fourth and latest in MediaTek’s flagship mobile SoC lineup, offers a massive boost in performance with its second-generation All Big Core design built on Arm’s v9.2 CPU architecture, combined with the most advanced GPU and NPU for extreme performance in a super power-efficient design.

The Dimensity 9400 adopts MediaTek’s second-gen All Big Core design, integrating one Arm Cortex-X925 core operating over 3.62GHz, combined with 3x Cortex-X4 and 4x Cortex-A720 cores. This design offers 35% faster single-core performance and 28% faster multi-core performance compared to MediaTek’s previous generation flagship chipset, the Dimensity 9300. Built on TSMC’s second-generation 3nm process, the Dimensity 9400 is up to 40% more power-efficient than its predecessor, allowing users to enjoy longer battery life.

“The MediaTek Dimensity 9400 will continue furthering our mission to be the enablers of AI, supporting powerful applications that anticipate users’ needs and adapt to their preferences, while also fueling generative AI technology with on-device LoRA training and video generation,” said Joe Chen, President at MediaTek. “As the fourth-generation flagship chipset, the Dimensity 9400 continues to build on our momentum of steady growth in market share, and MediaTek’s legacy of delivering flagship performance in the most efficient design for the best user experiences.”

Packing MediaTek’s 8th Generation NPU, the Dimensity 9400 boasts a number of industry firsts for exceptional generative AI performance; it is the first mobile chipset to offer on-device LoRA training, high-quality on-device video generation, and developer support for Agentic AI. To allow users to take advantage of the latest agentic and generative AI applications, the Dimensity 9400 offers up to 80% faster large language model (LLM) prompt performance while also being up to 35% more power efficient than the Dimensity 9300.

The Dimensity 9400 also integrates MediaTek’s new Dimensity Agentic AI Engine (DAE), which is designed to turn traditional AI applications into sophisticated agentic AI applications. MediaTek is working with developers to offer a unified interface between AI agents, third-party APKs, and models that efficiently run both edge AI and cloud services. This streamlined approach allows models to work with many different third-party APKs, which reduces development time and will help usher in a new ecosystem of agentic AI applications.

The 12-core Arm Immortalis-G925 delivers super immersive gaming experiences with up to 40% faster raytracing performance compared to the previous generation. The Dimensity 9400 also brings PC-level features to smartphones with opacity micromaps (OMM) support for realistic effects. The chipset’s powerful GPU also offers 41% peak performance boost with up to 44% power savings compared to the Dimensity 9300, allowing users to game for longer. Additionally, the Dimensity 9400 supports HyperEngine technology for super resolution and impressive picture quality, which is co-developed by MediaTek and Arm Accurate Super Resolution (Arm ASR).

With MediaTek Imagiq 1090, the Dimensity 9400 provides HDR video recording throughout the entire zoom range so users can snap the perfect moment from a distance; MediaTek’s Smooth Zoom technology also makes it easy to capture moving subjects. Additionally, it is designed to minimize power consumption while users are taking photos and videos, offering up to 14% lower power consumption in 4K60 video capture compared to the Dimensity 9300.
